2.8.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. It requires one of two
cables (not included in this package), depending on the drive size. 1.8"
and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5"
drives use a 1 x 44-pin to 2 x 40-pin connector.
Wire number 1 on the cable is red or blue, and the other wires are gray.
1. Connect one end of the cable to CN1 or CN7. Make sure that the
red (or blue) wire corresponds to pin 1 on the connector, which is
labeled on the board (on the right side).
2. Plug the other end of the cable into the Enhanced IDE hard drive,
with pin 1 on the cable corresponding to pin 1 on the hard drive.
(See your hard drive’s documentation for the location of the con-
nector.)
If desired, connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of the
cable. If you install two drives, you will need to set one as the master and
one as the slave by using jumpers on the drives. If you install only one
drive, set it as the master.
2.9 Solid State Disk
The PCI-6871 provides a 50-pin socket for CompactFlash card type I/II.
2.9.1 CompactFlash (CN28)
The CompactFlash card shares a secondary IDE channel which can be
enabled/disabled via the BIOS settings.
2.10 Floppy drive connector (CN6)
You can attach up to two floppy drives to the PCI-6871’s on-board con-
troller. You can use any combination of 5.25” (360 KB and 1.2 MB) and/
or 3.5” (720 KB, 1.44 MB, and 2.88 MB) drives.
A 34-pin daisy-chain drive connector cable is required for a dual-drive
system. On one end of the cable is a 34-pin flat-cable connector. On the
other end are two sets of floppy disk drive connectors. Each set consists
of a 34-pin flat-cable connector (usually used for 3.5” drives) and a
printed-circuit board connector (usually used for 5.25” drives).
